The story of the Isle of Atlantis first occurs in Plato's two dialogues the "Timaeus" and the "Critias." Plato's story centers on Solon, a great Greek legislator and poet who journeyed to Egypt some 150 years earlier. While in the Egyptian city of Sais Solon received the story of Atlantis from priests. The priests respected Solon's reputation and cordially welcomed him. They also respected the Athenians, whom they regarded as kinsmen, because they believed their deity Neith to be the same deity as the Greeks called Athena. Therefore, she was believed to be the patroness and protector of both Greece and Egypt.
The story that the priests told Solon was unknown to him. According to ancient Egyptian temple records the Athenians fought an aggressive war against the rulers of Atlantis some nine thousand years earlier and won.
These ancient and powerful kings or rulers of Atlantis had formed a confederation by which they controlled Atlantis and other islands as well. They began a war from their homeland in the Atlantic Ocean and sent fighting troops to Europe and Asia. Against this attack the men of Athens formed a coalition from all over Greece to halt it. When this coalition met difficulties their allies deserted them and the Athenians fought on alone to defeat the Atlantian rulers. They stopped an invasion of their own country as well as freeing Egypt and eventually every country under the control of the rulers of Atlantis.
Shortly after their victory, even before the Athenians could return home, Atlantis suffered catastrophic earthquakes and floods until it disappeared beneath the sea. All of the brave men were swallowed up in one day and night of horror according to legend. This is why the Egyptians were ever grateful to the Athenians.
Also in the story Plato gives is a history of Atlantis that shows how the rulers eroded to such a state were they wanted to conquer everyone. This history had been recorded by Solon in notes that were handed down through his family.
The best archaeological site for the fabled Atlantis is the island of Santorini which is essentially what remains of an enormous volcanic explosion, destroying the earliest settlements on what was formerly a single island, and leading to the creation of the current geological caldera. Some of the houses in ancient city of Akrotiri are major structures, some amongst them three stories high. Its streets, squares, and walls were preserved in the layers of ejecta, sometimes as tall as eight meters, and indicating this was a major town. In many houses stone staircases are still intact, and they contain huge ceramic storage jars, mills, and pottery.
Noted archaeological remains found in Akrotiri are wall paintings which have kept their original color well, as they were preserved under many meters of volcanic ash. The town also had a highly developed drainage system and, judging from the fine artwork, its citizens were clearly sophisticated and relatively wealthy people. Pipes with running water and toilets found at Akrotiri are the oldest such utilities discovered. The pipes run in twin systems, indicating that the Therans used both hot and cold water supplies; the origin of the hot water probably was geothermic, given the volcano’s proximity. The dual pipe system suggesting hot and cold running water, the advanced architecture, and the apparent layout of the Akrotiri find resemble Plato’s description of the legendary lost city of Atlantis, further indicating the Minoans as the culture which primarily inspired the Atlantis legend.
